Each Trial is a strategy a real species uses, turned into something you can run yourself in about ten minutes. Each card says what to do and why it helps.
Trials drawn from real behaviour
What each Trial asks you to do, and what it does for you. Reading a Trial needs no account. 3,017 Trials across 2,325 species. Showing 361–420.
2Gather cardboard, paper and offcuts you already have
3Build a first version that actually works
The Trial
Before buying or ordering anything for your next small project, build the first version entirely from the free abundant material around you: cardboard, paper, offcuts, spare time, things already owned. Finish a working first version from that alone.
Why it helps
Waiting on a purchase is usually waiting on a decision you have not made. Building the first working version from free material tells you within an hour whether the idea is worth spending anything on.
1Pick someone who would back you if things went wrong
2Do one real task for them, asking nothing back
3Tell them plainly you would back them too
The Trial
Pick one person you are not related to and not currently in conflict with, who would be on your side if something went wrong. Today, do one concrete thing for them with nothing asked in return - a real task, not a message - and tell them plainly that you would back them too.
Why it helps
Alliances built during a crisis are weak and everyone can tell. One real favour done for someone when nothing is wrong is what you will actually be able to draw on later.
Take something temporary you have been doing half-heartedly because it will not last, the short-term setup, the stopgap, the one-season thing, and do it properly today as if it mattered.
Why it helps
Doing temporary things badly because they will not last means most of your work is bad, since most things are temporary. Building it properly costs a little more and the whole season runs better.
3Helper scatters confetti until three pieces stick
The Trial
Twist fuzzy chenille pipe cleaners into a basket whose arms fork at least three times, bend the finest tips into small hooks, and keep it curled shut. Switch on a fan, open the basket fully into the airflow, and have a helper scatter pinches of tissue-paper confetti upstream so it drifts through; a missed pinch is simply scattered again until at least three pieces are held in the branches.
Why it helps
A satisfying build that makes branching structure and flow easy to see.
3Leave one hand-wide doorway, tape every other gap
The Trial
Choose something unfinished and easy to disturb that needs no light, such as a jigsaw, a model or a drawing, and build a cardboard box shelter over or around it. Fold or tear back one small flap as a doorway just wide enough for your hand, or cut it with round-tipped safety scissors only, and tape every other gap closed.
Why it helps
An unfinished project that pets, children and elbows can no longer wreck.
Make a small tactile or visual warning that alerts someone before they touch a harmless object, without requiring you to operate it. Photograph it working in place.
Why it helps
Practises preventative design: making the environment communicate a boundary before contact happens.
Push pencils, chopsticks or twigs upright into two lumps of modelling clay or a tray of soil to make two parallel walls about a hand's width apart. Place one favourite object at the far end of the avenue and arrange five smaller items at the entrance, then adjust them until the treasure is framed when you look down the avenue.
Why it helps
A charming small build that trains an eye for composition.
Gather only the ends and last bits already in your kitchen, such as bread heels, broken crackers, the last spoonful of a dip or the end of a cheese block, checking each is in date and safe to eat. Arrange them on one plate without cooking or heating anything, and set their empty or nearly empty packets beside it.
Transform one small corner you actually use into a deliberately striking display using things you already own. Keep rearranging until it looks intentional on camera.
Why it helps
One corner you use becomes one you actually enjoy looking at, using only what was already there.
Across a doorway, hallway, or garden gap, stretch string, yarn, or tape into a sparse open frame with a clear centre. Aim to cover the flight path of people or pets without filling the whole opening, then photograph the finished frame.
Why it helps
You learn to solve a catch problem with minimal structure instead of overbuilding.
Take something working that you were about to rebuild or restructure, and instead extend it from the outside without disturbing what is inside: add the wrapper, the extra shelf, the second sheet, the new section. Leave the working core untouched.
Why it helps
Rebuilding something that works means days of it not working. Adding a layer outside gets you the extra capacity today and the thing never stops running.
Name one lean or difficult stretch you can see coming. Build one concrete piece of shelter for it today, a prepared meal, a cleared evening or a set-aside amount, and put it where the lean stretch will find it.
Why it helps
Meeting a hard stretch empty-handed means every small problem inside it becomes a crisis you improvise through. One piece of shelter built in advance absorbs the first hit for you.
Before collecting anything else, make the empty container for it: the folder, the shelf, the labelled box, the document with headings and nothing under them. Build it empty, then put the first real thing in.
Why it helps
Gathering before you have somewhere to put things is why it all ends up in one pile. Building the empty container first takes ten minutes and everything after it lands in the right place automatically.
Build an accurate fix on one thing from a still position today, and do not commit until the fix is accurate enough to act on.
Why it helps
Committing before you have a fix means repeated attempts that each warn the target. Building the fix from stillness costs nothing and one attempt lands.
Take a source you have been treating as unusable because of one contaminant, the badly formatted data, the difficult person, the messy archive, and build the one filter that makes it usable. Then use it today.
Why it helps
Writing a source off for one contaminant leaves a large supply unused while you compete for clean ones. One filter built once turns it into something only you can draw on.
Take something you set up and then abandoned, and go back and tend it today: restart it, clear it, add the next input. Then stay with it for a set period rather than walking away again.
Why it helps
Setting things up and walking away is why you have a trail of half-alive projects. Going back to one and staying with it briefly is usually all it needed to start running on its own.
Find a capability you are paying to keep ready but have not used in months, the subscription, the standing slot, the kept-warm setup, and stand it down today. Note how you would rebuild it quickly if the need returns.
Why it helps
Standing capacity you are not using drains money and attention quietly all year. Shutting it down with a written route back costs nothing and you can rebuild in days if the need returns.
Make one dark, quiet, temperature-stable place today where you can do slow work: block the light, cut the noise, settle the temperature, and then do twenty minutes of deliberately slow work inside it.
Why it helps
Trying to work slowly in a bright, loud, hot room means you speed up to escape it and lose the quality. A place built for slowness lets you keep it.
Take one thing you keep getting by active effort. Build the structure today that catches it passively, a standing request, a filter or a recurring slot, then stop the active effort entirely.
Why it helps
Getting something by repeated active effort means you pay for it every time and lose it the week you are busy. One structure catches the same thing while you do nothing at all.
Pick one task today and do it in a single straight pass with no revisiting, no reordering and no going back to improve an earlier part, however much you want to.
Why it helps
Going back to improve earlier parts is how a one-hour task takes a day and still is not finished. One straight pass gives you something complete that you can then decide whether to improve.
2Push a deliberate volume through for fifteen minutes
3Count what piled up
The Trial
Take one thin stream of value you have been ignoring because each unit is too small to matter. Spend fifteen minutes today pushing a deliberate volume of it through, and count what accumulated.
Why it helps
Dismissing things because each one is too small to matter means you never find out what a concentrated hour of them adds up to. Counting the total once changes what you bother with.
Take an abundant low-value source everyone ignores and give it the full slow processing today rather than skimming it: read the whole thing, work the entire pile, sit with it for an hour.
Why it helps
Chasing rich sources puts you against everyone else chasing them. Giving the abundant ignored one real time gets you something nobody else has bothered to extract.
Take one problem you were going to approach alone. Gather the people involved into one place first today, close the gaps between your positions so you present one line, and only then move on it.
Why it helps
Advancing on something alone or with your people spread out means it picks off whichever position is weakest, usually yours. Closing the gaps first makes the whole group one thing it has to deal with.
With two or more people in an open room or yard, agree on a sharp clap or shout as the alarm. When it sounds, bunch shoulder-to-shoulder within three seconds, then run together to a pre-marked safe spot such as a bench or doorway line.
Why it helps
You practice fast coordinated relocation instead of freezing when a cue hits.
Pick a conversation, group chat or meeting you normally contribute to constantly. For one full hour, add nothing - no comment, no reaction, no opinion. Stay present and pay attention the whole hour, and at the end write down the three things you noticed that you would have talked over.
Why it helps
Constant input makes you miss what is actually happening in a room, including things that affect you directly. An hour of deliberate silence shows you information your own talking was covering up.

Burrow Under One Heavy Blanket for Fifteen Minutes
Lie on a sofa or bed, pull a heavy blanket or duvet over your body with arms and legs drawn in close, keep your face uncovered, put your phone out of reach on a time-lapse facing you, and stay settled for fifteen minutes.
Why it helps
A proper, guilt-free recharge when the day has been too much.
Outdoors only, lie face-down and flat on soft, level grass with at least fifteen metres clear in front of you, with a random-interval timer or a helper's clap as the approaching threat. The instant it sounds, whistle sharply, rise, make three stiff-legged two-footed bounds, then run low for about ten metres and stop to look back over your shoulder.
Why it helps
A thrilling reaction burst that trains you to go from total stillness to full speed.
Clear a three-metre lane on a non-slip floor, barefoot or in non-slip shoes, and set a chair with a cushion on its seat at the end in the open, with at least three metres clear beyond it and no wall or other furniture ahead. Lie flat with a light sheet over your head and torso only, legs free, start a random-interval timer or have a helper call go, then burst out, run upright and slap the cushion with one hand, then slow down past the chair.
Why it helps
Three seconds of pure adrenaline in your own living room.
Take one hard piece of work today. Push at it in one genuinely full-effort burst, then stop completely and get out of the environment it lives in before returning for a second burst.
Why it helps
Staying in the current between efforts burns you down without producing anything, which is why long days feel heavy and deliver little. Leaving the environment entirely between bursts is what makes the second one possible.
Take one flower bulb or one large seed, such as a bean. Wearing gloves, dig a hole in a pot of compost or a patch of garden about three times as deep as the bulb is tall. Put it in, cover it, press the soil down and water it. Push a label into the soil with today's date.
Why it helps
Slow work that nobody sees is easy to abandon. Putting something in the ground and agreeing not to check it trains you to leave long efforts alone long enough to pay off.
After doing something discreetly today, go back and remove the traces it left, the records, the artefacts, the residue, rather than only being discreet while doing it.
Why it helps
Being discreet while doing something and leaving your traces behind means it is found anyway, later and worse. Removing them takes you minutes.
Cover one exposed thing completely today in a single quick action before leaving it, with no part left partly covered.
Why it helps
Half-covering something before you leave is worse than nothing, because you stop worrying about it. One complete quick cover means you can actually go.
Pick one thing you have been actively chasing. Stop chasing it for today, position yourself where it passes anyway, and take it only if it comes within reach.
Why it helps
Chasing something tells everyone exactly what you want and raises the price of it. Putting yourself where it already passes gets you the same thing without the pursuit costing you anything.
1Chill your hands in cold water for thirty seconds
2Fasten five buttons while the timer runs
3Warm your hands in warm water for a minute
4Fasten the same five buttons again, timed
The Trial
Dip your hands in cold tap water for thirty seconds, dry them and fasten five buttons on a shirt laid flat while a timer runs. Then warm your hands in warm water for a minute, dry them, unbutton, and fasten the same five buttons again on the timer.
Why it helps
A quick, memorable way to feel why warming up before work matters.
Set up one permanent vantage point over something you keep checking manually: the dashboard, the pinned view, the single place where the state is always visible. Build it once today and use it instead of checking around.
Why it helps
Checking several places to work out the state costs you the same ten minutes every single day. One permanent vantage built once removes that for good.
Take something you have been trying to force through and spend today climbing to position instead: the relationship, the information, the standing, the timing. Do not attempt the move.
Why it helps
Forcing a move from a weak position costs you everything and usually fails anyway. Time spent getting above it means the same move takes almost nothing.
Walk a route through two or three rooms and tuck five wrapped snacks out of sight at five different points along it. Do something else for ten minutes, then walk the route once and recover all five inside sixty seconds.
Why it helps
A quick memory game that shows how well you already know your own home.
Hide five small tools, such as tape, string, a rubber band, a pencil and a cable tie, in five different concealed places around one room. Sit and rest for ten minutes, then collect all five in one pass from your seat, going straight to each spot.
Why it helps
A calm memory workout that leaves five handy tools gathered and ready.
Divide one packet of a snack into five small sealed portions and hide each out of sight inside a closed drawer, cupboard, box or under a cushion, in five different rooms or zones of your home and out of reach of pets and small children. Do something else for at least ten minutes, then start a visible timer and recover all five in one continuous run within two minutes, without notes or photos.
Why it helps
A fun memory test that ends with a snack you have properly earned.
Name one thing you want people to come to you for. Put a clear statement of it today somewhere genuinely public and visible rather than telling individuals, and leave it up.
Why it helps
Telling individuals what you can do means you reach only the people you already thought of, and you repeat yourself forever. One public statement left up works while you are asleep.
Take something you noticed today and said nothing about, then tell the specific person it actually affects, naming which kind of problem it is so they know what to do. Show the message or the conversation happening.
Why it helps
Noticing something and saying nothing leaves the risk exactly where it was. Telling the one person it affects, with enough detail to act, is the step that converts your attention into something useful.
Send something today to exactly the people who need it and nobody else, choosing the narrowest possible distribution rather than the convenient wide one.
Why it helps
Wide distribution feels safer and means everything you send is skimmed by people it was not for. Narrow distribution gets a real response and nothing comes back to bite you.
2Check in regularly, not only when something happens
3Keep it going through the whole stretch
The Trial
Keep one group in contact today through a stretch where you cannot see each other, checking in regularly rather than only when something happens.
Why it helps
Going quiet through the stretch where nobody can see each other is when your group comes apart. Regular contact through it costs seconds and holds everyone.
Pick two different spots, such as a bookshelf and a plant corner. Dress a shoebox only with loose items from the first spot until it blends in there, then carry it to the second spot, strip it and redress it using only what is found there.
Why it helps
A playful design challenge that trains you to read a space before you fit into it.
Do one thing today that people in your position are assumed not to do, and use it to get out of a situation you cannot win conventionally.
Why it helps
Playing a contest the way your category plays it means losing to whoever is better at that. One unexpected move ends it without you being better at anything.
Pick one change you have made and lost three times already. Today make the slowest, most permanent version of it you can: write it on the wall, change the physical object, cancel the subscription, give the key away. Something that will still be in place in a month without you maintaining it.
Why it helps
Changes that rely on you remembering them fail the first bad week, every time, and you lose the ground again. One slow permanent change holds while you are not paying attention.
Pick a simple tune or phrase everyone knows. You start alone, the second person joins two lines later on a different part or a round, and the third joins after that, so all three voices overlap for the final line.
Why it helps
A daft, joyful few minutes that bonds a household quickly.
Identify the short window in which something you have been maintaining all year actually gets decided, and put a disproportionate share of today's effort into that window.
Why it helps
Spreading effort evenly across a year where a few weeks decide everything means you are tired and unremarkable in both. Loading the window is how the whole year pays.
List what currently protects you, the contract, the savings, the relationship, the reputation, and mark which ones you built and which came from circumstance. Then do one thing today to secure a circumstantial one.
Why it helps
Protections you did not build can disappear without you doing anything wrong, and you will not see it coming. Marking which are which takes ten minutes and tells you exactly what to shore up.
Lay a rope, belt or line of tape about three metres long on a clear floor as the branch, and tape three paper leaves to the edges of chairs or a table beside it at about hip height. Hug a two-kilo bag of flour or rice against your chest with one arm and walk the rope slowly from end to end, taking at least one minute on a timer in view and pausing to pluck each leaf with your free hand.
Why it helps
A calm, loaded balance drill that steadies the ankles and the core.
With a consenting partner, link little fingers and walk one slow lap of a room or hallway while you carry two half-full cups of water, plastic if you have them, and your partner carries nothing. At the end, hand one cup over for your partner to drink.
Why it helps
A slow, silly, careful minute together that nobody spills if you get the pace right.
Roll three paper cones as deep flowers, dust the inside of the first with a pinch of cocoa or bright spice as pollen, and put a drop of juice at the bottom of each as nectar. Wrap a pencil tip in cotton as your gecko snout and push it to the bottom of flower one, then straight into flowers two and three.
Why it helps
A tidy little experiment that makes an unusual island partnership easy to see.
